Abstract

This paper examines the effectiveness of adaptive computational grids based on the concept of the equidistribution method for the problem of a transverse turbulent flow around a cylinder with a square cross section. Turbulence modeling is carried out based on the two-fluid turbulence model of Z.M. Malikov for the Reynolds number Re = 21 400. To confirm the correctness of the numerical results, a comparison is made with experimental data taken from the published sources. It is shown that as a result of using adaptive meshes, it is possible to improve the numerical accuracy for the given number of node points by condensing them in the required areas.
